I'm new to CAS and am scheduled for a "New Shooter Orientation" this month. I have two guns, a Stoeger 12ga and a Marlin 1894CB that I have recently acquired. I fired the shotgun a few months back at the Trap range and while it worked flawlessly, I was not able to hit many clays. I really bought the gun for CAS however and I expect that it will be fine for that purpose. I find that I am drawn more and more however to an 1897 Winchester; we'll see.
As for the Marlin; I went to the range yesterday and fired it for the first time. My groupings were good but a little low and to the right. This was from a standing position and unsupported, so I don't plan on making any adjustments just yet. The action on the Marlin seemed a little less smooth than what I expected, perhaps more lubrication is needed. I have read that many shooters have their guns "slicked up" but I'm not ready to do that yet. In any case, I am so far well pleased with the Marlin. I also fired my Heritage Arms .22 caliber SA for the first time yesterday. A nice little gun and it seemed relatively accurate. I have read recently that some clubs have side matches for .22's; I guess I'll find out in a few days if the club I will be attending does this or not.
